[APD] RUGF versus UGF
T. Barr said: "I've had RFUG's for 10 years with plants."
Why a RUGF versus a UGF?
Just curious since I recently installed a version of a UGF in my
90 - Perforated PVC pipes under a sheet of plastic insect screen
under the substrate, piped back to a submersible pump that is
pulling the water down through the substrate. I could reverse
that flow to push water up through the substrate, but why?
